Down 59-58 in the closing seconds of overtime, Sheridan set a screen for Ray and slipped behind the defense to get an inbounds pass under the hoop. Eagles forward Sean Williams was late getting over and charged with goaltending when he batted the shot away with 2.3 seconds left, giving Villanova the lead.

Louis Hinnant's desperation 3-pointer at the buzzer missed everything, allowing the Wildcats to escape with a 60-59 victory Friday night. They advance to play Florida in the Minneapolis Regional final Sunday.

"I turned around on the inbound and wondered how this man got open like that," Williams said. "So I get there and I didn't make it, I guess."

Foye carried the load for most of the game, scoring 29 points and playing all 45 minutes to offset a horrendous night from Ray and the rest of Villanova's vaunted four-guard lineup.

Foye scored six straight points for top-seeded Villanova (28-4) at the end of regulation, then added a 3-pointer and tough driving layup in overtime for a 58-55 lead.

"He was exhausted," Villanova coach Jay Wright said of Foye. "I said, 'Do you have more?' He said, 'It's my career. I have got it.' He was the best."

Jared Dudley and Craig Smith came right back with layups, the last one by Smith with 12 seconds to go to give No. 4 seed BC a 59-58 lead.

On the ensuing possession, Foye was foiled on a drive to the hoop and 'Nova took the ball on an inbounds play under its own basket. With the Eagles (28-8) blanketing Foye on the play, Sheridan sneaked in for the open look -- the same play that beat Cincinnati earlier in the year.

The Villanova faithful leaped out of their seats after the goaltending call, hoping their Wildcats might be headed back to the Final Four for the first time since Rollie Massimino's underdogs shocked Georgetown for the national championship in 1985.

It was a heartbreaking loss for Boston College, which controlled the game for the first 35 minutes.

But playing in their first regional semifinal since 1994, the Eagles also looked every bit the newcomers. They committed 21 turnovers and had a hard time getting stars Smith and Dudley into the offense, despite an overwhelming height advantage.

"I can't explain," a somber Smith said. "It is pretty tough. ... It was a tough loss losing by one. Not much you can say."

(11) GEORGE MASON 63, (7) WICHITA STATE 55: Lamar Butler dribbled out the final seconds of George Mason's latest improbable victory, then dropped the ball and wagged eight fingers toward a TV camera.

As in, "Round of eight, here we come!"

Butler hopped and skipped to the locker room, yelling over and over: "We're not even supposed to be here!"

Playing a short drive from George Mason's campus, Folarin Campbell scored 16 points and the 11th-seeded Patriots used a shutdown defense to beat Wichita State in Washington, D.C., in a mid-major matchup, and play Connecticut Sunday for a trip to the Final Four.

"We've been trying to prove ourselves all year. We heard what the critics were saying -- that we didn't belong in the tournament," senior guard Tony Skinn said. "The confidence level has risen, and we've gotten a chance to show the country what we're capable of."

Wichita State finished 20-of-64 on field-goal attempts, including a startling 3-of-24 on 3-pointers. The tone was set early, as George Mason broke out to a 9-0 lead and took a 35-19 edge into halftime, thanks in large part to Wichita State's 9-of-30 shooting from the field to that point, 1-of-11 on 3s.

(3) FLORIDA 57, (7) GEORGETOWN 53: Florida's Corey Brewer made one basket in the second half, and he made it count.

Brewer's tiebreaking, falling-down shot and subsequent three-point play with 27.5 seconds left lifted the third-seeded Gators to a victory over Georgetown in the Minneapolis Regional semifinals.

Brewer and rest of Florida's super sophomores are erasing memories of the Gators' recent tournament failures. The Gators hadn't been past the second round since 2000.

Joakim Noah had 15 points, 10 rebounds and five blocks in yet another all-around effort.

"I want to thank Corey Brewer for saving my butt, because I missed a wide-open layup at the end," Noah said. "Corey's play -- not to say anything against Corey -- a lot of luck comes into making a shot like that."

Taurean Green scored 13 points, and Al Horford added 12 points to give the Gators what they needed to get past the tenacious Hoyas (23-10).
